MAX3082ESA Transceiver: Circuit, Pinout, and Datasheet

One driver and one receiver are included in the MAX3082ESA high-speed transceiver for  RS-485 / RS-422  communication. When the receiver inputs are open or shorted, the device's fail-safe circuitry ensures a logic-high receiver output. If all transmitters on a terminated bus are deactivated, the receiver output will be a logic high (high impedance).

Reduced slew-rate drivers in the MAX3082ESA  reduce EMI and reflections produced by incorrectly terminated cables, allowing error-free data transmission up to 115kbps.

Higher driver output slew-rate limitations are available on the MAX3082ESA.  allowing transmission speeds of up to 500kbps. The MAX3082ESA  's driver slew rates are unrestricted, allowing for transmitting speeds of up to 10Mbps. When empty, or when fully loaded with the drivers disabled, these transceivers typically draw 375A of supply current.

All devices have a receiver input impedance of 1/8 unit load, allowing for up to 256 transceivers on the bus. The MAX3082ESA  is a half-duplex communication device.
